pinctrl: intel: Check against matching data instead of ACPI companion

2022-08-25T09:45:44+00:00

[ Upstream commit c551bd81d198bf1dcd4398d5454acdc0309dbe77 ]

In some cases we may get a platform device that has ACPI companion
which is different to the pin control described in the ACPI tables.
This is primarily happens when device is instantiated by board file.

In order to allow this device being enumerated, refactor
intel_pinctrl_get_soc_data() to check the matching data instead of
ACPI companion.

pinctrl: intel: Fix kernel doc format, i.e. add return sections

2022-05-20T14:02:21+00:00

Kernel doc validator is not happy:

  pinctrl-intel.c:865: warning: No description found for return value of 'intel_gpio_to_pin'
  pinctrl-intel.c:904: warning: No description found for return value of 'intel_pin_to_gpio'
  2 warnings

Add return sections to the kernel documentation of the above mentioned
functions.

pinctrl: intel: Drop unused irqchip member in struct intel_pinctrl

There is no users of irqchip member in struct intel_pinctrl. Drop it.

pinctrl: intel: make irq_chip immutable

2022-05-18T12:42:10+00:00

Since recently, the kernel is nagging about mutable irq_chips:

   "not an immutable chip, please consider fixing it!"

Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new
helper functions and call the appropriate gpiolib functions.

pinctrl: cherryview: Use GPIO chip pointer in chv_gpio_irq_mask_unmask()

2022-05-17T16:35:10+00:00

The callers already have dereferenced pointer to GPIO chip, no need to
do it again in chv_gpio_irq_mask_unmask(). Hence, replace IRQ data pointer
by GPIO chip pointer.

Since recently, the kernel is nagging about mutable irq_chips:

   "not an immutable chip, please consider fixing it!"

Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new
helper functions and call the appropriate gpiolib functions.

While at it, switch hwirq variable to use the correct type for
the sake of consistency.

pinctrl: broxton: Add module alias for Intel Apollo Lake

We have platform device IDs for Broxton and Apollo Lake, but
module alias is provided only for the former. Make it consistent
by providing an alias for Apollo Lake.

pinctrl: alderlake: Fix register offsets for ADL-N variant

2022-04-06T09:54:43+00:00

It appears that almost traditionally the N variants have deviations
in the register offsets in comparison to S one. This is the case
for Intel Alder Lake as well. Fix register offsets for ADL-N variant.
